FIELD OF THE INVENTION The Intensive Use Furniture relates to molded furniture for use in applications of high use in indoor or outdoor environments such as, health care and hospitality facilities.
BACKGROUND OF THE INVENTION Molded furniture intensive use furniture is designed for use in demanding environments. Facilities housing individuals for recreation or rehabilitation from health or legal problems require comfortable aesthetically pleasing furniture for safely furnishing living quarters, while being durable. Concealed fasteners for assembly and attachment to floor or wall protects the furniture and the user. The furniture must be assembled and attached to a floor or wall without providing removable parts that may be used as a weapon or tool. Securing the furniture to the floor or wall may further reduce safety concerns of both guests and hosts resulting in a safer environment.
Intensive use furniture may be attached to a floor or wall to prevent movement and use of the furniture to cause damage or injury. In the prior art, furniture may have been bolted to the floor or wall or ballasted with weight to make the furniture too heavy to lift. Assembled multipart furniture may have used threaded fasteners as well to attach components such as an arm rest on a chair. Using threaded fasteners to assemble or attach furniture to a floor or wall may offer an opportunity for a user of the furniture to remove the threaded fastener, such as a bolt, and sharpen an end to use as a weapon. Attempts to hide the fasteners may be overcome by persistent users or prevent moving the furniture without damage. Adhering the furniture to the walls or floor may damage the wall or floor and time may degrade the attachment as the adhesives age. Further such gluing down or hiding fasteners may create problems when the facility manager needs to rearrange the furniture.
Intensive use furniture such as disclosed in Karl U.S. Pat. No. 8,007,059 B2, entitled Intensive Use Furniture is created by rotational molding for durability and ease of cleaning. Such creative manufacturing eliminated fasteners for assembling furniture components. But, the traditional bolt down through a flange on the bottom of side walls may leave the head of the bolt exposed on the top of the flange. The one piece, one color furniture unit is not desired for uses such as hospitality and guest services. Therefore, to provide creatively designed furniture, separately manufactured components and additional aesthetic features such as wood-grain and multi-color effects and recessed fastening enabling fixtures, molded into the furniture, make the product more desirable while protecting the user and others.
Wood-grain effect molded into the furniture provides a pleasing aesthetic making the molded furniture seem more comfortable. By creating a contoured pattern on top of a base shell, with a contrasting color, in a molding process may produce simulated, naturally occurring designs such as wood-grain, stone and other external surface finish designs. These aesthetic designs protect the user and facility. The design is part of the molding process and may not separate while in use. No fasteners such as adhesive is used to attach the surface design. The integral molding of the surface design may reduce manufacturing time and labor to produce.
Multi-color molding using techniques such as zone-control within the mold reduce the labor and cost to produce. By producing an integrally molded multi color product, no assembly fasteners or labor may be needed. Molding one area of the furniture component at a time by selectively heating predefined zones of a mold prior to adding plastic resin, reduces manufacturing time and provides a durable product having integrally molded colors together in a one piece furniture component.
Therefore, it is desirable to provide safe furniture for such facilities with aesthetically pleasing characteristics and design for comfortable use. Therefore there is a need to provide an intensive use furniture product without exposed fasteners and designed for concealed, releasable attachment to a mounting surface such as a wall or floor.
BRIEF DESCRIPTION OF THE PRESENT INVENTION The Intensive Use Furniture is a molded furniture design having a surface attach design which may attach the furniture by a concealed attachment device fixing the furniture to a bracket. For purposes of description, the surface attach design shall be discussed as a floor mount. It should be understood, the surface attach design may be adapted to attach to a wall as well. The recessed link may be a keyed ball pin or a tamper resistant fastener. The floor attach may prevent movement of the furniture in an x, y or z axis direction, that is the x axis may be left to right, y axis may be forward and backward and z axis may be up or lifting the furniture. The floor bracket may include a floor mount portion and a furniture interface portion. A mounting tab on the furniture may be adapted to engage the floor bracket. The x-axis mounting tab engaged with the floor bracket may prevent x-axis or z-axis movement. A y-axis link on the furniture shell may be adapted to engage the floor bracket. The y-axis link attached to the floor bracket may be adapted to prevent y-axis or z-axis movement of the furniture. A tab mount portion molded into the furniture may be adapted to receive the x-axis tab.
The tab mount portion may comprise a shaped landing portion, a finger hole and a furniture bolt hole. The x-axis mounting tab may comprise a generally flat bracket portion, a finger link and a tab bolt hole. The bracket portion having a furniture end, a bracket end, a floor surface and a furniture surface. The furniture end and the bracket end aligned in a generally y axis orientation. The furniture surface on the shaped landing portion. The finger link on the bracket portion comprising a first end on the furniture surface and a second end spaced from the furniture surface. The second end extending into the finger hole. A threaded fastener extending through the tab bolt hole into the furniture bolt hole. The threaded fastener having a head bearing on the floor surface whereby the x-axis mounting tab is retained on the furniture.
The y-axis link may be aligned in a generally x-axis orientation. The y-axis link may be on the furniture and attached to the floor bracket. y-axis link The y-axis link may use a means to attach to fix the furniture to the floor bracket. The means to attach may include a threaded fastener, a ball pin or other device on the furniture and removably attached to the floor bracket. The y-axis link may have a tamper resistant interface. The tamper resistant interface may be a tamper resistant head or a keyed actuator or other means.
The furniture skin may comprise a plurality of layers. The skin is formed in a mold having a surface effect mold portion comprising a first predetermined relief pattern etched in the product surface to simulate a desired surface finish. The mold may further comprise a structural effect mold portion comprising a second predetermined pattern etched in the product surface to simulate an assembly of boards or rocks making up the furniture. The furniture skin may comprise one piece penetration resistant shell comprising a surface effect furniture portion and a structural effect furniture portion. The surface effect furniture portion on top of the structural effect furniture portion whereby the outer skin may appear to be formed of boards, the boards having a wood grain pattern thereon. A thin, outer, soft touch layer of a clear or translucent polymer such as poly-ole-fin. A surface effect layer under the soft touch layer may comprise a wood grain effect comprising a thin layer of plastic having a first color. The surface effect layer may comprise a translucent layer. The skin may further comprise a base layer of a plastic such as polyethylene having a second color. The base layer may further comprise inner support ribs extending into the shell. The inner support ribs disposed adjacent to the second predetermined pattern contours to imitate rocks or board shapes. These rock or board shapes The skin may further comprise a foamed layer inside of the polyethylene layer. The foamed layer comprising ribs extending away from the polyethylene layer. The ribs generally aligned with the contours in the polyethylene layer. Integrally molding a surface design saves time and money but the results must look authentic to provide an aesthetic impression. While rotational molding is known in the prior art as charging a closed, heated mold with a polymer and rotating the mold for a predetermined time at a predetermined temperature profile, the method used to make intensive use furniture having a wood-grain finish comprises the steps of:
provide a mold for use in rotational molding, the mold comprising an interior surface, the interior surface comprising an etched portion, the etched portion comprising material removed to form a predetermined design on the interior surface;
provide a liquid polymer;
heat the mold to a first temperature;
provide a wiper for use with the liquid polymer;
